Chapter 9.9, Problem 20PPS

To determine

To calculate: To graph the function

Explanation of Solution

Given information: Function is $y=4^x$

Calculation:

Function is given as

  $y=4^x$

When $x=0$

  $y=4^0=1$

When $x=1$

  $y=4^1=4$

When $x=-1$

  $y=4^{-1}=\frac{1}{4}$

When $x=2$

  $y=4^2=16$

When $x=-2$

  $y=4^{-2}=\frac{1}{16}$

Function table is

x	y
-2	$\frac{1}{16}$
1	$\frac{1}{4}$
0	1
1	4
2	16

Plotting the points on graph:

  

Conclusion:

Hence, graph is plotted
